題目： Evolution Systems and Continuity Equations forWhite Noise Functionals

日時：令和４年１１月２３日（水）１６：３０～１７：３０

場所：名城大学共通講義棟東E７０２室

要旨：

　In this talk, we start with an application of the continuity equation

to the optimal transportation problem. By applying the quantum

decomposition of white noise functionals, the continuity equations

for white noise functionals are reformulated as time inhomogeneous

white noise differential equations.

We establish a systematic study of the evolution systems whose

infinitesimal generators are quadratic quantum white noises and

then as an application, we study the continuity equations for white

noise functionals of which the coefficient has up to the first chaos

(Gaussian process).

The restriction for the coefficient is comparable (not necessarily

equivalent) to the integrability condition of the exponential of the

coefficient by Ambrosio and Figalli for the well-posedness of the

continuity equation in the abstract Wiener space setting.
